SPECIFICATION forming part of Letters PatentfNo. 705,478, dated July 22, 1902. Application tiled December 26, 18,99. Serial No. 741.591. {No model.)

To ctZZ L11/71,0711, it' may concern:

Be it known that we, MATTHEW STOBBS and JOHN SEYMOUR THOMPSON, subjects of the Queen of Great Britain, residing at Sydney,

New South Wales, have invented new and.

D and particularly pointed out in the claims.

In the drawings, Figure 1 is a side View of' the invention; Fig. 2, a'plan View; Fig. 8, a detail rear view of the casing and brush; Fig. 4, a sectional view along the aXis of the casing. Fig. 5 is a sectional'view from front to rear of the apparatus. Fig. 6 isa detail View.

In the drawings, ka, represents the cart- Wheels, rotating on suitable axles b, which support a frame c. On these axles angle-levers d are fixed. VThe horizontal arms e of these levers support a shaft f. The ends-Of this shaft projectvinto guideways ctof segmental form secured to the frame c. The shaft f supports a casing g of substantially cylindrical form, the hubs it of said outer casing g being iixed to the shaft. This casing is open at top and bottom',`as indicated at ax and m, respectively, these letters denoting the points at which the cylindrical shell g of the casing is interrupted to leave the upper and lower openings. The casing g is made up of the said cylindrical shell g/ and the heads or side plates g, which are secured to the angle-iron rings j. This casing is adapted to turn axially; but' it is normally prevented from turning by means of a chain hf, connecting. the same with the frame. Within the said casing g a receiver 71, is arranged. This is made up of side plates o, a cylindrical shell o', angle-iron rings p, to which shell and heads are connected, and hubs or bushes q, which are fixed to the side plates o and are keyed to the axle f. The cylindrical shell is cut away or interrupted at r at the top of the receiver to leave an opening at thisl point. Between the receiver hand the outer casingvgg a conveyer operates. Thisconsists of side plates or headss, carried bya bush or hub u, adapted to rotate about" the hubs k of the relatively fixed outer casing g. The plates s are con- .Yangle-iron rings i forming extensions of the said shoulders, said bolts connecting, by means of nuts z, with the plates S, and thus Securing the blades to the plates s. Distance-ferrules Y are preferably arranged between the rings w and the It will be seen that the receiver h is of substantially cylindrical form. It is of smaller diameter than the casing g,

`and being concentric thereto an annular or substantially annular space is left between the casing` and the receiver in which the series of blades V move. These blades are arranged radially infrespect to the axle f. The whole series of blades with the plates s, carrying the same, are to rotate, and for this purpose they project through the lower opening at m, so that the plates Contact with the ground, andthus turn as the apparatus is drawn forward. At the rear lower part of the outer casing a brush n is fixed. This lies immediately attherear of the opening at m, and as the apparatus is drawn forward the dirt collected bytheI brush will be gathered up by the blades V and carried up between thecylindrical shells g' and o', and upon arrivingat the opening fr of the inner receiver the dirt will be discharged into the same and will be held thereby, as the bottom of this receiver is closed. The outer casing is kept closed at its upper part by a sliding door Z of segmental form, which is adapted to be slid over the said opening While the machine is in operation collecting the dirt.

The long arms bof the angle-levers d are connected at their upper ends by a cross-rod c, which is connectedby a cord e with a drum d', journaled in the frame a and provided with a ratchet f at one end. The ratchet is arranged to be engaged by a pawl g to hold the drum against* turning backwardly.

A hook k is pivoted tot e frame togengage the cross-bar c' when the same'isibrought thereto when it is desired to lift the receiver IOO - proximity to the ground, an inner stationary and outer casing from the ground. When this is to be donc, the drum d' is turned by a `suitable crank and the outer casing is raised. In this raised position the parts may be held by causing the hook or pawl 7c to engage the cross-rod c. The apparatus may now be drawn freely in order to carry the load obtained to the dumping-place. When the apparatus is to be dumped, the rope e/ is unfastened from the cross-rod c', and this end is carried beneath the outer casing g and attached onto some point, as E. Upon turning the roller (the outer casing and receiver remaining elevated) the said outer casing and receiver will be rotated about their common axis, so that the openings at r and dx of the said receiver and outer casing will be lower most, and thus the contents of the receiver will be discharged.

Vv'e claim as our inventionl. In a combined road-cleaner, elevator and dirt-cart, an outer stationary casing supported in proximity to the ground and having an open lower portion, an inner stationary receiver arranged concentric therewith forming an annular space between, said receiver having an open upper side, radially-arranged blades located in said annular space, and means for causing said blades to travel through said space,substantially as described.

2. In combination, an outer stationary casing having an open lower side supported in receiver arranged concentric therewith with an annular space between, and spaces at the euds, said receiver having an open upper` portion, heads or plates jourualed in the spaces between the ends of said casing and receiver, l

and radially-arranged blades carried by said heads and fitting said annular space, substantially as described.

3. In combination, an outer stationary casing having an open lower side supported in proximity to the ground, an inner stationary receiver arranged concentric therewith with an annular space between, and spaces at the ends, said receiver having an open upper portion, heads or plates journaled in the spaces between lthe ends of said casing and receiver, and radially-arranged blades carried by said heads and fitting said annular space and means for raising said casings from the ground, substantially as described.

4. In combination, a frame, supportingwheels journaled therein, angle-levers pivotally mounted in said frame, an axle carried by said angle-levers, astationary cylindrical casing carried by said axle having an open lower side, a cylindrical receptacle within the casing also carried by said axle having an open upper side, heads or plates journaled on the axle between the ends of the casing and receptacle and projecting through the open side of the casing for contact with the ground, radial blades carried by said heads and fitting the annular space between the peripheral walls of the casing and receptacle, and means for rocking said angle-levers, substantially as described.

In witness whereof we have hereunto set our hands in presence of two witnesses.
